My exhaust must have shifted in the past few years or something, but I have a small quarter sized carbon spot from where my bumper came in contact with my hot exhaust tip and melted it on there. Cooked it to a carbon spot over a years time. It's a stainless exhaust from Perrin.
Anyone have any suggestions? I could scrape it off.. possibly. Doubt it would work well and not sure if it'd scratch the surface. I could also blow torch it. Something not too hot like a propane torch, not Mapp or anything. Unsure if that would do anything either.
Edit: I meant removing melted plastic from bumper on my exhaust.
